David We had a very high Hi-Q failure rate and the test h said we three options,1, in advance send in the failed unit. Wait till one is available to release to the RMA, 3, buy extras so we dont need to wait and they had plenty in stock to sell but not to be the RMA. That really was my final straw. You might want to look at segmentating the combiner and going with manageable inverters, what AC side voltage are you running. Jerry
